  1. 405. In Search for an Optical or Infrared Counterpart to Neutron Star Mergers
    Mansi Kasliwal
    19/01/2022, 09:00
    We are all enjoying the dawn of a new era with multiple direct detections of gravitational waves from merging black holes and eagerly a waiting a merger with at least one neutron star. Here, I will present my ongoing efforts and my view on prospects to identify and characterize an electromagnetic counterpart. Among the various models for electromagnetic emission from binary neutron...

  5. 409. EM counterparts from NS-NS, BH-BH and WD-WD mergers
    Maxim Lyutikov
    19/01/2022, 11:00
    We discuss electromagnetic signals expected from mergers of various compact stars, stressing the ''Faraday wheel'' mechanism of converting mechanical energy into electromagnetic.

  6. 410. Machine learning for gravitational wave electromagnetic counterparts
    Michelle Lochner
    19/01/2022, 11:30
    Since the first direct detection of gravitational waves in 2015, a new window of discovery in Physics has opened up. However, in order to use gravitational waves as probes of cosmology and fundamental Physics, an electromagnetic counterpart must be detected. As the sky localisation for a gravitational wave detection is large, detected transient sources from follow-up and...

  7. 411. High energy radiation from jets and accretion disks near rotating black holes

  8. 412. Transients from magnetically active compact objects
    Andrei Belbodorov
    19/01/2022, 14:00
    Magnetized compact objects are capable of generating strong intermittent outflows resembling coronal mass ejections from the sun. Internal shocks in these outflows can produce bright transients with a broad spectrum. This activity should be especially strong for differentially rotating objects formed in mergers. For instance, white dwarf mergers should produce bright transients, even...

  9. 413. What GW detections can tell us about jet structure of short GRBs
    Gavin Lamb
    19/01/2022, 14:30
    The peak magnitude for orphan afterglows from the jets of gravitational wave (GW) detected BH/NS-NS mergers highly depends on the jet half-opening angle. For a short GRB with a homogeneous jet structure, the jet half opening angle that gives an orphan afterglow viewed at the typical inclination for a GW detected event, 38 degrees, that is brighter at optical frequencies than...

  10. 414. Binary Black Hole Mergers from Field Triples: Properties, Rates, and the Impact of Stellar Evolution
    Silvia Toonen
    19/01/2022, 14:45
    I'll be present our recent paper on black hole mergers that occur due to secular evolution in stellar triples. I'll show the expected rates and characteristics and what sets them apart from other formation channels.
